Self-deprecatingly, he jokes:
"I got used to this a long time ago with Newcastle!"
Pavel is delighted to be at Upton Park, having effectively replaced Rami Shaaban following his return to Arsenal after a month's loan, and he says:
"I feel good being here; I had a session and a talk with the manager and I am enjoying it here - I don't think there are any problems."
Could he stay longer?
"We haven't discussed these things yet," he says, "because I am here for a month and we will see how it goes afterwards.
"The situation is at it is at Portsmouth but it is not the best solution for me; this is a good chance and I have taken it."
Does he know Steve Bywater?
"He hasn't been playing for a long time so I don't know him too well, but I met him and he is a nice lad.
"There is competition for places, which is normal."
Pavel is a Czech compatriot of goalkeeping coach Ludek Miklsoko - so what language will they be using?
"I speak to him in the language which is written in my heart - the Czech one!"
Pavel will also be able to communicate in his mother tongue with Tomas Repka, and he adds:
"He is a good defender; I have played with him on many occasions for the national team and at club level as well so we know each other."
